Why was AVX/SSSE3 gsdx config removed? or am I misunderstanding this buildbot commit? Sad
nope I downloaded the latest build v1.5.0-dev-1856.. and the AVX/SSSE3 plugins are missing... Sad

I use the GSDX AVX plugin for my gfx plugin since it works well with my
AMD FX™-9590 Eight-Core Processor which has the following exts..
[MMX(+), SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, SSE4A, x86-64, AMD-V, AES, AVX, XOP, FMA3, FMA4]


Code:
v1.5.0-dev-1848-g754045b     Jonathan Li     2017-01-26 00:42:05     No build     gsdx:windows: Remove SSSE3 and AVX configurations

please re add these ext by reverting that commit as my cpu does not support AVX2... Sad

Do you have an issue when using the SSE4 plugin?

idk..  will GSdx32-SSE4.dll be compatible with any of my cpu's SSE4 configs?  SSE4.1, SSE4.2, SSE4A

with AVX I'm getting the most out of my CPU...

I did a quick test switching config from AVX to SSE4, it loaded fine... so...

SSE4 and SSE4.1 are the same thing, so yes it'll work.

AVX in our testing has shown to be no faster, maybe marginally at most, but that could be margin of error in difference.

ok, so I take it you are not going to retract the removal of AVX/SSSE3 right?
I guess I'm using SSE4 from now on... Wink

Thought AVX was only faster in software mode while it performed the same as sse4 in hardware mode?

That's for AVX2.

Could have sworn that was being kicked around the forums before AVX2 came out

For one my i5 3570k doesn't support AVX2 but it does support AVX tho.

Or have changes since then made the difference smaller then it use to be?

SW renderer will pick up avx automatically even on sse2 build. So having an avx only plugin is moot
